Blend the ingredients:
Add the white rum (if using), pineapple juice, coconut cream, and ice to a blender. Blend on high speed until smooth and creamy.
Taste and adjust:
Taste the mixture and adjust the sweetness by adding more pineapple juice if needed. For a thicker consistency, add more ice.
Serve:
Pour the Piña Colada into a chilled cocktail glass.
Garnish:
Add a pineapple wedge, a maraschino cherry, and a sprinkle of shredded coconut on top. Finish with a cocktail umbrella for a festive touch.
Mocktail version:
Follow the same steps, omitting the rum. Add a splash of sparkling water for a bubbly twist, if desired.
